Answer:

<h2>3.5</h2>

Step-by-step explanation:

We can find the constant of proportionality by finding the value of y when x = 1.

y = 3.5 when x = 1

The constant of proportionality, y/x, is 3.5/1 or just 3.5.

Which expressions are equivalent to Negative 9 (two-thirds x + 1)? Check all that apply.
Sav [38]

<u><em>Answer:</em></u>

<u><em /></u>-9(\frac{2}{3}x) + 9(1)\\  \\-6x + 9

<u><em>Explanation:</em></u>

<u>Before we begin, remember the following rules:</u>

<u>1- Distribution property:</u>

<u />a(b+c) = ab+ac

<u>2- Simplification of fractions:</u>

<u />\frac{xy}{yz}=\frac{x}{z}

<u>3- Signs in multiplication:</u>

+ve * +ve = +ve

-ve * -ve = +ve

+ve * -ve = -ve

<u>Now, for the given problem, we have:</u>

<u></u>9 (\frac{2}{3}x + 1)

<u>Starting with the distributive property:</u>

<u />-9 (\frac{2}{3}x +1) =  -9(\frac{2}{3}x) - (-9)(1) = -9(\frac{2}{3}x) + 9(1)

..................>This corresponds to option 1

<u>Now, we simplify the output from the above step:</u>

<u />-9(\frac{2}{3}x) + 9 = \frac{-9*2}{3}x + 9 = -6x+9

................> This corresponds to option 5

Hope this helps :)

2 divided by negative 1/5
oksian1 [2.3K]

Answer: 10

you have to find a common denominator between two and five which is 10. therefore making the number 2 into the fraction 20/10 and finding the common denominator of 1/5 makes it now 2/10. now divide 20 by 2 which gets you 10. and dividing 10 by 10 gets you. therefore making the new fraction 10/1 which is equal to 10. :)

The length of an object is measured as 45.8 centimeters. What is this measurement in scientific notation?
inna [77]

Answer:

4.58 * 10 cms.

Step-by-step explanation:

The general form for scientific notation is

N * 10^n      (where 1 ≤ N < 10 and n = an integer).

45.8 = 4.58 * 10^1  or 4.58 * 10.

WILL GIVE BRAINLIEST ANSWER TO WHOEVER ANSWERS FIRST AND CORRECT
Daniel [21]

Answer:

The answer is -2.5.

Step-by-step explanation:

This is because the distance between -9 and 4 is 14 units. And the two numbers in the middle are -3 and -2, so -3 plus -2 equal -5 and -5 divided by 2 equals -2.5.
